A check of the message that arrived

Paste a whole message.

One real campaign, headers and body. The check names what the receiver recorded, which domains signed it, whether they align with From, whether one-click unsubscribe is genuinely present, and what the body reveals about consent and content law.

Easier: send it to us. Finding and copying a raw message source is a power-user move. Sending an email is the one thing every marketer can already do, and it produces exactly the same findings.

Send us your actual campaign

The paste is parsed in this request. We keep the findings, the From domain and two dates — no body, no subject, no recipient, no raw headers.

Paste the copied original, headers first. Include the body and you also get the postal address, tracking, summary-text and subject-line findings — not only the authentication ones.

The message is parsed and dropped. Only the findings are kept.

Before you paste

Get the raw message, not a summary.

Forwarding the email or copying the visible details removes the evidence this check needs.

  1. Gmail. Open the message, choose ⋮ → Show original, then Copy to clipboard.
  2. Outlook. Open the message, choose … → View → View message source.
  3. Apple Mail. Choose View → Message → Raw Source.

Headers alone still work. You get the authentication findings and nothing about the body, because there is no body to read.

What this proves, and what it does not. We read the signature; we do not recompute its cryptography. Only a receiver can do that against the message it accepted. An Authentication-Results header is that receiver's verdict, so this check prefers it over its own alignment inference. The HTML is read for facts and never rendered, and no link in it is followed.
